Minimal Virtual Reality System for Virtual Walking in a Real Scene

摘要

Various sensory stimuli are required to accomplish a fully virtual walking system because walking is related to multimodal sensations. We developed a minimal virtual walking system and evaluated it using psychological factors. The system consisted of a real-scene optic flow and rhythmic foot vibrations. We tested the effects of vibrations synchronized with optic flow and the size of the visual field on the sensations of virtual walking and found that synchronized, two-channel foot vibrations with a 3-D optic flow elicited the virtual walking sensation. A larger visual field enhanced the footstep sensation during walking.
